Mujoco renderer error

[Aristomo]

I just run the sample code in the tutorial of python bindings,

import mujoco
xml = """







"""
model1 = mujoco.MjModel.from_xml_string(xml)
data = mujoco.MjData(model1)
renderer = mujoco.renderer.Renderer(model=model1)

Then there is an error:

Exception ignored in: <function GLContext.del at 0x000002BE7D526670>
Traceback (most recent call last):
File "D:\anaconda\lib\site-packages\mujoco\glfw_init_.py", line 41, in del
File "D:\anaconda\lib\site-packages\mujoco\glfw_init_.py", line 35, in free
TypeError: 'NoneType' object is not callable

Maybe because I did not initialize the render? How to solve it?

Did anyone find any fix for this?

You can remove the "()" behind the "free" function in "glfw_init_.py" and the position can be located if you click the error information.

Hello @Amritpal-001, @Aristomo
to solve this problem, you can install Mujoco 3.1.1 and then use one of the below options:

`

Option 1.

renderer = Renderer(...)
// use renderer
renderer.close()

Option 2.

with Renderer(...) as renderer:
// use renderer`

for example :
renderer = mujoco.Renderer(model)
renderer.close()

this works for me
